4 Claims.

This invention relates to what are sometimes called multi-section cars, or articulated cars, and which comprise two or more sections having car bodies with adjacent ends articulated to, and carried by a common truck, and the principal object is to provide an enclosed passageway bridging the gap between adjacent car ends.

Further objects and advantages of the invention will appear as the disclosure proceeds and the 10 description is read in connection with the accompanying drawings, in which Fig. l is a diagrammatical view in perspective of two adjacent car ends, separated from the truck and displaced to reveal the pasageway and suggest the manner of assembly shown inv Fig. 3;

These specific constructions having been built and put into satisfactory operation, are used for the purpose of disclosure, but not with the intent of imposing unnecessary limitations on the claims.

In Fig. 1, ii! and i I indicate car bodies, adjacent ends of which are to be articulated and supported upon a common truck [2, as shown in Fig. 3, by center plates 63 and i4 cooperating with the truck, The car body ii) is provided with a vestibule pas sageway unit or structure, including a floor or tread l5, curved side walls It, and a flat top ll, all fixed to the car body to project from it in cantilever fashion and be received within a corresponding doorway recess in the car body H.

In Fig. 2, i8 and I9 indicate similar car bodies,

the adjacent ends of which are carried by a common truck 20, shown in Fig. 4, through center plates 2| and 22 cooperating with the truck. In this instance the car body [8 is provided with a vestibule passageway unit, or structure, including a floor or tread 23, curved sides 24, and a flat top 25, anchored on the car body and projecting from it to enter a corresponding doorway opening in the car body l9, when brought into the relation shown in Fig. 4.

The constuction diagrammatically shown in Figs. 1 and 3 is more fully illustrated in Figs. 5 to 8 (Sheets 2, 3, 4 and 5).

Each car body includes a transverse end sill 25, which, together with longitudinal sills 27, 28, 29 and 39, and corner posts 3! and ribs 32, covered with side and roof sheathing 33, form the car body.

The top of each sill Z6 is provided with flanges 34, to which are secured hollow built-up door posts each including a V-bar 35, an irregularly shaped bar 36, and a plate 31, which together form the main portion of the post, and one duct 38 for the passage of air in the air conditioning system of the car.

Near the top of car section H all the components of the door posts, except the irregularly shaped bar 36, terminate at and are secured to a stout transverse plate 39 (Fig. 7), sometimes called the antitelescoping plate, from its function of resisting shock in collisions. Bar 35 extends to the roof as shown in Fig. 8. Inv car section [0 the post components are secured to the plate 39, and continue above it to the top ll of the passageway to which they are made fast.

As best shown at the left in Fig. 1, the antitelescop-ing plate 39 has a curved edge to, inwardly of which, and extending upwardly from the plate 39, is a curved end plate H, joined to the roof by an angle 42, Figs. 5 and 7.

The door posts of the car body it include, in addition to the bars 35, 3E and plate 21, two upright plates i3 and 4 5, which, together with the bars 35 and 35, form another duct 45,

In the car body H a similar duct 46 is formed by the cooperation of an angular plate 4'! with the corresponding bars 35 and 36.

From the description thus far it will appear that the pairs of door posts, with the corresponding end sill and anti-telescoping plate, form door- 0 way openings separated by a gap, which it is the purpose of the vestbule passageway structure to span and provide safe passage for passengers from one car body to the other.

The floor l5 of the passageway rests upon and is secured to the end sill 26 of the car body l0, and forms a continuation'of the floor 48 of that car, as indicated particularly in Figs. 5 and 7.

The top H of the vestibule passageway is fitted against the curved wall 4| of car section (Fig. and secured by an angle 49, from which it projects to end in a curved edge stifiened by an angle 50.

The curved side walls l6 of the passageway are fixed at the upper end to the top I 1 and the antitelescoping plate 39 by angles 5|, 52 and 53, and to the floor by an angle 54 and a filler plate 55. They also have flat flanges H6 overlapping the plates 44 (Fig. 6) and built into the door post structure.

From this it willbe clear that the vestibule passageway is in the nature of a cantilever through bridge, anchored to the car body l0 and projecting beyond its end, toward the car body i I.

The door posts of the car body ll form a doorway opening into which the floor or tread l5 of the vestibule unit projects above the corresponding end sill 26 to terminate in substantial alignment with a tread plate 56 at the edge of the floor 48. The top H of the vestibule passageway laps over the anti-telescoping plate 39 of the car body H, the curved edge of which is stiffened by an angle 51, provided with a weather strip 58 cooperating with the underside of the top I! to make a weather seal.

The free edges of the curved walls l6 of the vestibule unit are connected with the plates 41 of the door posts in the car body II by bent sheets of flexible material, 59, such as weather-proofed canvas, rubbenand the like, secured at its edges by screws, or other fastenings 60. V

The vesitbule passageway and its load are borne entirely by the car body I0, and the clearance between the floor or tread l5 and the end sill of the car body I I, and the clearance between the top i 1 and the anti-telescoping plate39 of the car body H, permit the necessary movement as the articulated car goes through a depressed portion of the track. 7

The floor, or tread I5 is provided with a hinged trap door 6| to permit inspection of the body center bearing, the truck center bearing and the associated parts, the construction of which is sufficiently revealed in the drawings for the purpose of this application.

The form shown diagrammatically in Figs. 2 and 4 is more particularly disclosed in Figs, 9, 10, 11 and 12, (Sheets 6, '7 and 8). r 7

The car body [8 includes an end sill 62, center sills 63, side sills 64 bowed ribs 65, and a sheathing 66, that forms the covering for the sides. and the top. Overhead there is a box beam structure 61 connected with the end sill by fabricated columns or posts 68, made up'of special extruded shapes, but not here of great importance. These posts are set apart to leave a doorway passage fitted with a door frame'69.

The car body 19, which was built as a power section in this particular embodiment, includes a somewhat similar construction, except that the posts 68 are replaced by channel shaped posts 19, setapart to define a doorway passage. The floor or tread 23, the curved side wall 24, and the top 25 of the vestibule passageway, are secured togetherto vform a generally cylindrical drum shaped unit. 7 7

On the lower'side the bottom is fitted with a disk H welded or riveted in place, and havingan opening to receive a bolt 12 by which the vestibule passageway is made fast to a bracket 13,

mounted on the end sill 62 and projecting somewhat beyond it, as shown in Fig. 9, to support the vestibule assembly substantially in alignment with the axis of the truck center bearing 14.

Bent plates 15 and 16 are secured to each of the columns 68 and made fast to the adjacent In this position the passageway structure pro-' jects in cantilever fashion from the end of the car body 18, and the floor, or tread 23, extends over the end sill 63 of the car body I 9 with ample clearance to permit the necessary movement in traveling through a valley in the track.

The end sills are fitted with curved angles 83 carrying weather strips 84 rubbing against the underside of the vestibule floor to make a weather seal,

The top 25 of the vestibule assembly has a curved angle 85 (Fig. 9) cooperating with the weather strip 86 carried by a'plate 8! secured to the anti-telescoping plate 88 on the car body I9. The free edges of the passageway walls 24 are connected to the posts 10 by flexible sheets, or strips 89, of waterproof canvas, rubber, or the like, to form a weather seal. Y

The floor, or tread, of the vestibule passageway fits with appropriate clearance between the curved tread plates 90 and 9| of the car floors.

It might well be made one with the tread plate 98, but for convenience in manufacture for this particular embodiment the vestibule passageway structure was fabricated as a separate unit and ing rearwardly. The car' body I8 is equipped with i a flexible -fiy 93 of weather-proofed fabric, rubber, or the like, secured at its rear edges to the roof and side sheets at 94 and at its front edge to a bow 95, carried by pivoted arms 96 mounted on brackets 91 at the sides of the passageway walls 24 and urged forwardly by springs 98 stretched between arms 99 on the brackets 91 and lugs 10 on the arms 96. V

The feature of construction and the general fabrication of the car bodies, trucks and articulation, form the subject matter of other pending applications.

The two embodiments disclosed were especially designed for light weight construction, chiefly of aluminum alloy.

I claim:

1. In an articulated car, a truck, car bodies with adjacent ends carried by the truck, and a passageway between the bodies comprising a cantilever structure, including a floor tread member, projecting beyond the car body from one of the adjacent ends into the other, the entire weight of the passageway being carried by the first mentioned car body 2.
